Des scientifiques ont r\u00e9ussi \u00e0 transmettre puis lire des informations quantiques pour la premi\u00e8re fois. Une \u00e9tape cruciale pour le d\u00e9veloppement des prochains r\u00e9seaux Internet plus rapides et plus s\u00fbrs.<\/strong><\/p>\n

Alors que nous sommes encore loin du 100 % fibre optique voulu par le gouvernement<\/a>, le monde scientifique travaille d\u00e9j\u00e0 depuis plusieurs ann\u00e9es au r\u00e9seau Internet de demain<\/strong>. Vous avez s\u00fbrement au moins entendu parler de la th\u00e9orie physique sur laquelle il se base : la m\u00e9canique quantique<\/strong>. Pour r\u00e9sumer, il s'agit de l'\u00e9tude des<\/strong> comportements des particules \u00e0 l'\u00e9chelle des atomes<\/strong> et plus petit. Les ph\u00e9nom\u00e8nes observ\u00e9s peuvent servir \u00e0 d\u00e9velopper des choses tr\u00e8s concr\u00e8tes : une batterie qui se recharge sans fil \u00e0 la dur\u00e9e de vie infinie<\/a>, un trou noir miniature sur Terre<\/a>, un ordinateur 100 millions de fois plus rapide que n'importe quel autre<\/a>… Et donc un nouvel Internet.<\/p>\n

Ce r\u00e9seau du futur sera plus rapide que la fibre optique et plus s\u00e9curis\u00e9<\/strong>, tout en permettant des op\u00e9rations extr\u00eamement complexes<\/strong>. Il pourra optimiser les d\u00e9cisions financi\u00e8res globales<\/strong> ou cr\u00e9er des mol\u00e9cules<\/strong> par exemple. Mais avant d'en arriver l\u00e0, il y a un probl\u00e8me majeur \u00e0 r\u00e9soudre. Sur l'Internet quantique, les informations transmises sont quantiques elles aussi, logique. Sauf que plus elles parcourent de distance, plus elles perdent des donn\u00e9es<\/strong>. C'est \u00e9galement le cas actuellement, et c'est pour cela qu'on utilise des r\u00e9p\u00e9teurs<\/strong> qui lisent puis amplifient le signal avant de le lui faire continuer son chemin. Impossible de les utiliser avec les donn\u00e9es quantiques : ils les d\u00e9truisent<\/strong>. Mais des chercheurs ont trouv\u00e9 la solution.<\/p>\n
